Not quite. They require you to collect at least two pieces of *evidence* of

I'd just use any plausible free GeoIP database I could blag a copy of, or even
just query whois.ripe.net and parse out the country: field. Unless you're
wilfully negligent, this should be sufficient. It already sounds like you're
going way beyond the minimum level of checks acceptable, so I wouldn't worry
